QToolBarAreaLayout: replace inefficient QLists with QVector

QToolBarAreaLayout{Item,Line} are larger than a void*, so holding
them in QLists is needlessly inefficient. Worse, the code could
come to depend on the fragile property of (inefficient) QLists
that references to elements therein never are invalidated.

Fix by marking the types primitive and movable, resp., and
holding them in QVector instead.
